There is a very accurate way to see if the moon is in the sky above the horizon after sunset. Apollo missions left 3 mirrors on the moon. Their exact locations are known. Anybody can shine a laser beam on them and get a reflection back after 2.6 seconds (Moon is 384,403 km away from Earth and light travels at 300,000 km/sec).
